Over on 'Mark Watches' the review for Human Nature is up.
Spoilers (and the Doctor's full directions to Martha) are below.
EDIT: Okay, now that I'm back from class I see that this has jumped the gun a bit. Anyone know what time Mark usually puts up his 'Watches' reviews? I have the next week of posts all written up and I want to get them scheduled to appear roughly at the same time as Mark's do so I don't have to worry about stalking Mark's site between classes.
